Formation of self-ordered porous anodized alumina template for growing tungsten trioxide nanowires

Formation of porous silicon through the nanosized pores of an anodized alumina template

Electrostatic capacitance of TiO2 nanowires in a porous alumina template

Titanium oxide (TiO2) nanowires were prepared for an electrolytic capacitor application by the automatic dipping technique using a porous alumina template. The automatic dipping technique allows us to exactly control the dipping rate so that we can obtain homogenous infiltration of nanowires in the porous alumina membrane, even though the solution is very acidic. From the TEM, SEM and XRD measu...

Fabrication of a tungsten master stamp using self-ordered porous alumina

We describe the preparation of a tungsten pillar nanoimprint stamp without the use of lithography and etching techniques. Structures with heights of 15 nm were prepared on the basis of self-ordered porous alumina templates and this was followed by DC sputtering of tungsten. The stamp was successfully used to prepare an aluminium surface to obtain highly ordered porous anodic alumina films after...

Selective formation of tungsten nanowires

We report on a process for fabricating self-aligned tungsten (W) nanowires with polycrystalline silicon core. Tungsten nanowires as thin as 10 nm were formed by utilizing polysilicon sidewall transfer technology followed by selective deposition of tungsten by chemical vapor deposition (CVD) using WF6 as the precursor. With selective CVD, the process is self-limiting whereby the tungsten formati...

Ordered Nanomaterial Thin Films via Supported Anodized Alumina Templates

*Correspondence: Mohammed Es-Souni , Institute for Materials and Surface Technology, University of Applied Sciences, Grenzstrasse 3, Kiel, Germany e-mail: [email protected] Supported anodized alumina template films with highly ordered porosity are best suited for fabricating large-area ordered nanostructures with tunable dimensions and aspect ratios. In this paper, we first discuss important issues...
